Psychology 101 Exam 3 Test

1. How does stress impact brain function?

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

2. Rita shows better control over her eating habits at 2.5 years than her brother Richard did at the same age. Why?

Correct answer: D

Rationale: The correct answer is D because boys typically develop gross motor skills, like running and jumping, more quickly than girls. This can explain why Richard may have had less control over his eating habits compared to Rita at the same age. Choices A, B, and C are incorrect because they do not address the specific developmental aspect related to eating habits control mentioned in the question.

3. If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.

Correct answer: B

Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.

4. What term refers to the awareness that other people have their own intentions, desires, wants, and motives?

Correct answer: A

Rationale: The correct answer is 'Theory of mind.' Theory of mind is the understanding that others have their own thoughts, feelings, and intentions. This ability allows individuals to attribute mental states to others, enabling them to understand and predict behavior based on those mental states. Choices B, C, and D are incorrect because they do not specifically address the awareness of others' intentions, desires, wants, and motives.

5. Which of the following statements is least likely to be made by a humanist?

Correct answer: B

Rationale: The corrected question assesses the least likely statement made by a humanist. Choice B, 'The behavior of humans tends to be influenced by environmental circumstances,' is least likely to be made by a humanist. Humanists believe that human behavior is not simply dictated by environmental circumstances but is influenced by a combination of factors, including personal experiences, emotions, and conscious decisions. Choices A, C, and D are more aligned with humanist perspectives. Choice A acknowledges the uniqueness of humans, which is a common theme in humanistic psychology. Choice C reflects the humanistic belief that individuals strive to reach their full potential and self-actualization. Choice D contrasts with humanist views as humanists often consider research on animals to be relevant in understanding human behavior due to shared basic psychological processes.
